UNITED STATES PATENT OFFICE.

ISAAC GRIFFIN, OF MILFORD, GEORGIA.

IMPROVEMENT IN COTTON-PRESSES.

Specification forming part of Letters Patent No. 3 1,079, dated January8, 1861.

To all whom it may concern,.-

Be it known that I, IsAAc GRIFFIN, of Milford, in the county of Bakerand State of Georgia, have invented a new and useful Improvement inCotton and other Presses; and I do hereby declare the following to be afull, clear, and exact description thereof, reference being had to theaccompanying drawings, forming part of this specification, and in which-Figure 1 represents a plan View of my press, and Fig. 2 a section online x x of Fig. l.

Similar letters of reference to each of the several figures indicatelike fparts in the drawings.

To enable others skilled in the art to lnake and use my invention, Iwill proceedto dcscribe its construction and operation.

A is the frame of the machine; B, the screw; C, the levers, to which thepoweris attached; D, a' platform rigidly secured between the posts A ofthe frame A, and through the center of which the screw B works.

E is a sliding or movable platform, movable up or down, as required,through the action ofthe screw B, which is attached thereto by a screwand nut, as shown, and to the under side of which arms or levers F areattached. These arms F are hinged to the movable platform at f, and tothe pressingblock G at j", as 'shown in dotted lines in Fig. l.

H is a box,77 into which the cotton is put to be pressed, swinging on acenter at 7L, and resting, to withstand the pressure of Ithe blocks G,(on the cotton inside,) against supports I, as shown.

J J are doors, which can be opened to allow the cotton, after havingbeen pressed, tobe bound and dropped out of the box into a receptaclebeneath. (Shown open in red lines in Fig. 2.)

The operation is as follows: When the platform E has been raised,through the agency of the screw B, as before explained, to its highestpoint of elevation,- the pressing-blocks .G will have been all drawn outof the boxes H and resting on ways k. These boxes H are -now at libertyto be npturned and filled with the required amount of cotton andreturned to their normal position. To prevent their going too farforward, the lower forward ends rest on a cross-piece, b. The horse orother power is now attached to the lever C andhinged on the under sideof the platform,

reach a certain'elevation on their downward pressure they exert aknuckle or wedge power, and act to support themselves in the pressureagainst the cotton, and consequently taking less expense of power topress the cotton where `the greatest pressure is required.

rlhe boxes H may be multiplied, and as many used as desired, stillretaining the same principle, by making the movable platform E ofAcircular shape and hinging the arms nearer the outside of said platformto accommodate more arms and prevent the interference of the posts A.

I do not claim a revolving box, as shown in the patent granted to H.Randle February 16, 1858; but

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The combination and arrangement of the screw B, movable platform E,a'rms F, and pressing-blocks G, with boxes H, as and for the purposesherein set forth and described.

IsAAo GRIFFIN.
